A number of participants suggested that there was scope for the formulation by treaty bodies of guidelines which would provide for an expanded core document including substantive areas common to each treaty, as well as statistical information, including difficulties in the collection of such information.
A juicio de algunos participantes, existía la posibilidad de que los órganos de tratados formularan directrices para un documento básico ampliado en que se tratasen esferas sustantivas comunes a cada uno de los tratados y se presentasen datos estadísticos, con indicación de las dificultades del acopio de tal información.
